EM Game Theory Discussion #1

over 6 years

Each Wednesday, I'm going to make a thread about a particular subject about Epic Mafia Game Theory.

Our first discussion will be about 3 way vs. 4 way.

When there is an even amount of players, if one kill and one lynch happens every night and day, when the game reaches critical point, it will be a MYLO with meteor on town so mafia can choose to no kill and not clear anyone.

However, this can be avoided by "NLing for 3 way" or "NLing to avoid 4 way" by having mafia choose a kill to make it 3 way.

There's definitely some reasons to avidly oppose and avidly support NLing for 3 way, and there's also different scenarios in which you may support one over the other.

Feel free to openly discuss when, and when not to NL for 3 way and answer the poll on your stance in general.

Please note that everyone will have various opinions and there's no right or wrong opinions. I want several opinions to fly but make sure that the conversation doesn't get too heated or I will have to mute you. Feel free to PM me recommendations for next week's game theory topic.

On average, how imperative do you feel is it for town to NL if they are in a 4 way scenario at day? Give your answer using a scale of 1-10
5
10 - Do it every time without fail.
2
8
2
1 - Never do it ever.

good that a new player posted, now try and explain patryk what you guys are talking about

The only questionable thing is 4way with a clear vs. 3way no clears. In this case, if I find the clear a noob - I try NL.

If there's a clearly less experienced player in the table alive in 4-way MYLO with no clears, the best thing to do is to immediately NL without speaking (or try goading the mafia into killing in some way, without breaking the rules of course--but this usually doesn't work) and hope the less experienced player is mafia, and kills somebody. This can be used by a better player as WIFOM, however.

In most instances, no kill will occur in this circumstance, and town will have to scumhunt on 4-way MYLO with no clears with meteor on them.

As for the poll and answers, it needs to be specified more as to whether or not there are clears, imo. Otherwise there isn't enough information to properly answer. Good topic though soda

all this discussion is pointless unless you engage new players because they literally play like bots

Below is a general loose algorithim for what to do on 4-way MYLO:

Preface: You always want as few unclears as possible with one or more clears (except for 4 way mylo with one clear with nothing gained through the clear's death--in this situation, all living players can determine if a 3 way lylo with no clears is better than the 4 way mylo with 1 clear. This is case-by-case, situation dependent).

Here is the algorithim:

If there are no clears:

If meteor on town: (Forced to) lynch

If meteor on mafia: NL

If there is 1 clear with nothing gained through their death:

If meteor on town or mafia: Meteor generally won't come into play here, so lynch usually, unless everyone else doesn't trust the clear to do it right or the living players think a 3 way lylo with no clears gives town better winning chances. This is completely situation dependent (case by case). This was the situation noted earlier in the preface.

If there is 1 clear with something gained through their death:

Depends on the power role and this would take too long to discuss for every role, but generally town wants them to die so town gets some type of advantage that they didn't have before out of it.

If meteor is on mafia: Then either mafia kills the PR, or...

...they kill somebody other than the PR if they can't kill the PR (or if they don't want to kill the PR). Different possibilities here.

If meteor is on town: (Forced to) lynch

If there are 2 clears (assuming neither's death gains anything for town

If meteor on town of mafia: Either NL or lynching is fine, regardless of who has meteor. One clear or two clears can make a decision. But keep in mind the mafia can kill the "better" clear or the clear who seems to be closer to winning the game for town. Two clears alive leads to disagreements sometimes, however.

If you question is just blues and a mafia, then 1 time.

4 way with Gunsmith:

Pr(Gunsmith hammers Mafia) = 0.33

Pr(Gunsmith guns Town) = 0.66
Pr(Town hammers Maf) = 0.5
Thus

Pr(Gunsmith guns Town and Town hammers Maf) = 0.33

According to game theory, same winrate.


But idk, as GS in that situation, its a lot easier to find someone you TR than to find mafia you fos.

And then as town, when its between 2 people, its easier again to find out who you hammer. So I would always NL and GS gun someone.

It's kinda tricky for me -- there's several variables.


I'll say about it more once I come back from lectures.



With gunsmith alive and an even number of players alive, you do not EVER no lynch. Period end of statement.


Agreed with an exception of hooker setup and 4way.



With doc alive and an even number of players, you also never no lynch. Doc can save into a mislynch.


It depends... Keepin mind that mafia can hit doc and you're screwed.



In VDLI if BP gets hit, I'll normally just acquiesce to no lynching, but I don't think it's usually the best idea. If it's on night 1 mafia can sac orc if they have a lucky stalk, if it's on night 2, mafia SHOULD sac orc if town nls.


Mafia usually finishes off the BP. I rather not keeping this mylo.



I really have no qualms with 4 way. Yeah, your odds of winning the 3 way are better, but think about every 3 way scenario you enter when mafia is forced to kill the prior night. It ends up being either a clear PR or a universal townread. So in 3 ways there's no backbone to depend on.


I like bones.



Also another thing why 4 way is better is because in 5-way it is so easy for scum to blitz if votes aren't properly done. In 6-way, it's very difficult for mafia to blitz.


Sounds legit when you play in noob table.

Let’s discuss meteor this week instead. someone wake up Connor

you'll have to tell me why because the gun is literally a mislynch


it lets the GS gun his townread which is easier

In 4 way with GS I support NL.
In 4 way with Doc I do not support NL.

game theory turns out to be a really poor framework for understanding the game of epicmafia

you're much better off using frameworks from psychology than mathematics


do not talk arts on our good STEM website sir

- What defines a "scumslip" and a "townslip"


we should do this and then discuss why i second guessed myself and didn't just shoot you into town autowin
over 6 years
Here's some ideas for next week

- Faking guilties
- Nilla or lawyer ccing cop in A&D/A&V
- Roleswapping
- CCing your role when it's claimed
- Alignment before name in cop reports
- Fungunning/vesting
- Hipfiring
- Sacrificing yourself as scum when necessary
- Coding
- Bussing
- WIFOM
- Meta
- Fallacies
- What defines a "scumslip" and a "townslip"
- AtE
- Meteor

(Guilty testing is an idea as well, but I've recently made a thread about this).

Depends on situation :doge: Don't NL with clears. If they're semiclear then just flip flop around until time runs out and mafia blitzes. Otherwise NL if you have a bunch of silly blue noavis.
